We now read and write the century byte in the max6900 chip. We probably don't need to do so on Linux-only system, but it's necessary when the chip is shared by another OS that uses the century byte. Signed-off-by:

Various people have expressed surprise that their modular RTC drivers don't seem to work for initializing the system time at boot. To help avoid such unpleasantness, make the Kconfig text point out that the driver probably needs to be statically linked. Signed-off-by:

The version of SLOB in -mm always scans its free list from the beginning, which results in small allocations and free segments clustering at the beginning of the list over time. This causes the average search to scan over a large stretch at the beginning on each allocation. By starting each page search where the last one left off, we evenly distribute the allocations and greatly shorten the average search. Without this patch, kernel compiles on a 1.5G machine take a large amount of system time for list scanning. With this patch, compiles are within a few seconds of performance of a SLAB kernel with no notable change in system time. Signed-off-by:

After discussing w/ Thomas over IRC, it seems the issue is the sched tick fires on every cpu at the same time, causing extra lock contention. This smaller change, adds an extra offset per cpu so the ticks don't line up. This patch also drops the idle latency from 40us down to under 20us. Signed-off-by:

We need to make sure, that the clockevent devices are resumed, before the tick is resumed. The current resume logic does not guarantee this. Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock event devices before resuming the tick / oneshot functionality. Fixup the existing users.

Call chain causing oops: run workqueue dec_pending bio_endio(...); <remove device request - remove mempool> mempool_free(io, cc->io_pool); This usually happens when cryptsetup create temporary luks mapping in the beggining of crypt device activation.

Jan Harkes authored
This is an variation on the patch sent by Christoph Hellwig which kills file_count abuse by the Coda kernel module by moving the coda_flush functionality into coda_release. However part of reason we were using the coda_flush callback was to allow Coda to pass errors that occur during writeback from the userspace cache manager back to close(). As Al Viro explained on linux-fsdevel, it is impossible to guarantee that such errors can in fact be returned back to the caller. There are many cases where the last reference to a file is not released by the close system call and it is also impossible to pick some close as a 'last-close' and delay it until all other references have been destroyed. The CODA_STORE/CODA_RELEASE upcall combination is clearly a broken design, and it is better to remove it completely. Signed-off-by:

Trying to survive an allmodconfig on a nommu platform results in many screen lengths of module unhappiness. Many of the mmap related things that binfmt_flat hooks in to are never exported despite being global, and there are also missing definitions for vmalloc_32_user() and vm_insert_page(). I've implemented vmalloc_32_user() trying to stick as close to the mm/vmalloc.c implementation as possible, though we don't have any need for VM_USERMAP, so groveling for the VMA can be skipped. vm_insert_page() has been stubbed for now in order to keep the build happy.

If the swiotlb maps a multi-slab region, swiotlb_sync_single_range() can be invoked to sync a sub-region which does not include the first slab. Unfortunately io_tlb_orig_addr[] is only initialised for the first slab, and hence the call to sync_single() will read a garbage orig_addr in this case. This patch fixes the issue by initialising all mapped slabs in io_tlb_orig_addr[]. It also correctly adjusts the buffer pointer in sync_single() to handle the case that the given dma_addr is not aligned on a slab boundary. Signed-off-by:
